[PATCH 0/4] LoongArch: KVM: Code cleanup about feature detect

Posted by Bibo Mao 1 week, 4 days ago

Here is code cleanup about feature detection, there is feature
initialization about host machine, feature checking about VM and host.

Also add register LOONGARCH_CSR_IPR during vCPU context switch, though
it is not used by msgint driver now, it is defined by HW and may be used
in future.

Bibo Mao (4):
  LoongArch: KVM: Move feature detection in function
    kvm_vm_init_features
  LoongArch: KVM: Add msgint registers in function kvm_init_gcsr_flag
  LoongArch: KVM: Check VM msgint feature during interrupt handling
  LoongArch: KVM: Add register LOONGARCH_CSR_IPR during vCPU context
    switch
